The Virtualization Practice

Business Agility

Business Agility covers using the technical agility delivered by virtualization and cloud computing to improve business agility, performance and results. This includes the agility derived from the proper implementation of Agile and DevOps methodologies, the agility derived from proper application and system architectures, ...
the agility derived from the proper implementation of Infrastructure as a Server (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) clouds, the agility derived from proper monitoring of the environment coupled with a process to resolve problems quickly, and the agility derived from have continuous availability through the use of high availability and disaster recovery products and procedures in place.

VMware’s “Squeeze the OS” Strategy – Open War with Microsoft and Red Hat

The announcement of CloudFoundry means the public declaration of full on war between VMware, and the two traditional OS vendors, Microsoft and Red Hat. Both traditional (not quite legacy yet) OS vendors are going to have to rapidly bolster their own PaaS cloud offerings. This will be a particular challenge for Microsoft as Microsoft has always gravitated strongly towards having a tightly integrated stack of software, and not being very open to open source frameworks like Spring, Ruby, and PHP.

Citrix’s annual Synergy conference held this week in San Francisco was kicked off with CEO Mark Templeton painting his view of the future, and the building and leveraging of cloud services. With the emergence and evolution of cloud services, Templeton believes that the industry has moved out of the PC (personal computing) era into a PC-3 era, incorporating personal, private, and public cloud services.

It is interesting to see Edward’s comment that according to EMC/VMware, widespread production deployment of Cloud Apps is 3-5 years off. If that is the case the VMware CloudFoundry initiative should be focused on cutting-edge development rather than porting existing apps, and in much the same way that Microsoft has always courted developers, CloudFoundry should be the latest cool thing for developer productivity. It’s interesting to talk about this stuff in the abstract, and at the strategic level, but sometimes it’s worth understanding what happens when you need to make the decisions for yourself.

Monitoring SQL Server Performance on VMware vSphere

Attempting to infer the performance of a database server by looking at resource utilization metrics will fail technically and organizationally. In a shared and dynamic environment, the only way to truly assess the performance of an element of the infrastructure or an application is to measure how long it is actually taking to do its job. This makes response time and its companion metric latency into the two most important metrics for virtualized and cloud based systems.

Amazon’s Service Level Agreement (SLA) is so narrowly-drawn that it could easily be argued that the recent Elastic Block Store (EBS) outage wasn’t a failure of Amazon Web Services at all. Anyone using EBS in a production environment was, arguably, reaping the fruits of their own folly. Of course they don’t tell you when you read the hype that architecting for resilience in the Cloud is actually very complicated, particularly if you want to take the sensible step of not relying on a single provider like Amazon, no-matter how dominant their hype may be.

I was reading the post Small Business Virtualization and that really got me thinking about Small to Medium Businesses and what part Cloud Computing will play in that market. There are plenty of small businesses in and around my area and I have a couple of friends that are the owners of a couple of these small businesses. A majority of these small businesses have a single or a couple of point of sale machines that feed to the accounting program. It is these businesses that I think of when I think of what a small business is. Would virtualization help these companies? Sure, I think so but would it really be worth the cost to setup and maintain?

VMware’s latest effort, CloudFoundry, is not about VMware delving into the PaaS market even deeper. They have done that already with VMforce. CloudFoundry on the other hand is a fairly astute move to enable the development and rapid adoption of cloud based applications. The end goal is to sell what makes up a PaaS environment which is more enabling software. This would enable enterprises and businesses to move to the cloud. The problem with them moving now is that there are not that many applications that are cloud friendly. In effect more concentration on the application and less on the operating system which has always been VMware’s strategic direction.
